All you need to do to perform this move is hold the right analogue stick in any direction and then release it.

This move comes in useful when you need to get away from defenders, it works exactly the same as a Jump Shot except you quickly release the right analogue stick before your player scores.

This is an easy shot to do and is effective against a variety of different players. To perform it you need to rotate the analogue stick in a quarter circle from your ball-hand to the hoop and then back to your ball-hand.

When you need to get rid of defenders the following trick which changes your shots in mid-air works well. To perform it you execute a normal Dunk or Layup and when your player reaches the mid-air point you hold the right analogue stick in any direction.
